2018 Mercedes-Benz C 2.1L Diesel · GD18 AEB

The vehicle remains roadworthy, but the maintenance trend shows a clear decline in attention to basic consumable components. The most recent test in September 2025 at 47,239 miles flagged both rear tyres as being worn to the legal limit and showing signs of perishing or cracking. This follows a pattern of neglect observed in the 2024 and 2023 tests, where tyres were consistently noted for uneven wear and low tread. The mileage profile is notably low for an eight-year-old vehicle, averaging approximately 5,900 miles per year. Data shows a clean period between 2021 and 2022 where no defects were recorded up to 28,342 miles. However, the vehicle has covered nearly 19,000 miles since the 2022 test, with the most activity occurring between recent tests. This low-use pattern often leads to rubber components drying out due to age, which likely explains the cracking and perishing noted in the 2025 advisory. A buyer must inspect the suspension geometry and alignment in person, as the recurring reports of tyres worn on the edges suggest potential alignment issues or worn suspension bushes. The 2023 advisory regarding thin rear brake pads at 33,490 miles indicates that service intervals are reactive rather than proactive. Given the age of the car and the low mileage, check for brake caliper corrosion on the discs and ensure the rubber seals and hoses have not suffered from long periods of standing stationary.
